What Customers Are Saying
The Fluidmaster Duo Flush System-Dual Flush Converter offers adjustable flush levels to help reduce water usage. However, many customers reported issues with the product's quality and durability, including the handle breaking, the mechanism failing to properly seal and causing leaks, and the half-flush feature not working well. Several reviewers also complained about the cheap, plastic construction and parts that broke down quickly.

Great product easy to install
Would RecommendInstallation was easy and instructions were accurate and understandable. I coupled this repair kit with Flushmaster 1.6-Gallon Tank Flush Valve(Item #: 134110 | Model #: 507AK). After the installation the toilet was very much quieter. I expect this will last for a very long time. I recommend changing out the flush valve and the rubber bushing between the tank and toilet.

Do Not Buy!
Would Not RecommendThe base does not seal properly, so toilets run constantly. The design does not allow enough water through, regardless of settings, to flush the toilet. This thing literally cannot flush a toilet.

Worked for about 10 flushes and then you had to adjust every other flush, not worth the $$$

Convenient
Would RecommendThis kit is very convenient and likely saves tons of water if used properly. The only downside is that after flushing, the tanks takes a long time to refill.

Don't waste your money on this product!!!!
Would Not RecommendWorked great for about 9 months. After 9 months this thing starts flushing on its own, tried adjusting the water levels, removed it and re-installed but nothing worked. Replaced it with a cheaper one from another vendor and so far no problems.

Great idea, universal flaw in cable
Would Not RecommendI have purchased two of these units in 3 years. I purchased the second because the cable broke on the first one. Yesterday, the cable broke on the second one. Simply not worth having to replace every 18 months or so. I have seen where the company offers to work with others that have this problem but since it's the weekend, we really can't wait until Monday to contact them and then wait a week to get things fixed. Sadly, a toilet is something we need each day and waiting simply isn't an opti...

toilet repair
Would RecommendThis product was easy to install and works well except I did have a question I called customer service about and their people were less than helpful and not real professional, there is a slight leak which lasts for 4 to seconds and they were not able to advise me as to what the problem might be

Water
Would RecommendEnergy conservation includes our water/natural resources. This Fluidmaster minimizes water/flush ratio.

Would RecommendAfter years of the old stopper; this regulator is accurate, quite and water conservative.

Product did not work for me
Would Not RecommendThe part that takes the place of the flapper did not seal properly and continued to leak. I ended up taking the unit back and replacing it with a standard fluidmaster unit.
